Locating Wall Furnace Consider the following points before attempting to install MINIMUM DIMENSIONS FROM VENT the furnace : ALL MODELS 1 . This is a direct vent wall furnace . It must be installed on an OUTSIDE WALL for proper venting of flue gases ( Fig . 1 ) . 2 . Wall furnace can be surface mounted on an outside wall up to 24 inches thick when using an optional VENT 3o . , , , EXTENSION KIT . 3 . Check the clearances needed from the furnace and vent ( Figs . 1 and 2 ) . You must place the furnace where you will have no less than the clearances shown . 4 . The outside vent must be at least 18 inches away from any window or other building opening . 5 . The furnace will not work if anything stops free entry of fresh air into the vent , or free flow of flue gases from it . Be sure the center of the vent cap is at least 12 inches above ground level or shrubs as shown in Fig . 1 . Make sure shrubs are kept trimmed . It must also be at least 18 inches from any wall or other blockage and 30 inches below any overhang . 6 . Try to place the furnace near the center of the space to be heated for good air circulation . Do not put it behind a door or draperies . Do not put in a closet , alcove , hallway or other confined space . 7 . Be sure that gas piping and electrical wiring ( optional INTERIOR CLEARANCES blower only ) can be brought to the furnace . See sec - tions on gas piping for your type of mounting . 8 . To provide adequate clearance and service access , the front of the furnace must face the open room . INTERIOR CLEARANCES ( Refer to Fig . 2 ) ( 1 ) 18 " MIN .
